Patent DE-3334119-A1 (DE)
Title: Rail fastening by means of an elastic strainer
Inventor: EISENBERG HELMLUT
IPC: E01B9/48
Filed: 1983-09-21
Abstract: The invention relates to a rail fastening with a rib plate and an elastic strainer made of bar steel in the form of a W, which is held by a fastening screw and the central part of which winds round the shaft of the fastening screw and, when pressed down, finds a clamping path limit with the rib of the rib plate, the free ends of the strainer, which run towards one another, pressing on the rail foot. The new rail fastening is characterised in that the central part (7e) of the strainer (7), which faces the rail (1), comes to lie a short distance above the rail foot (1a) and the adjoining regions (7b, 7c) on the opposite side of the clamping region (7d) are formed in such a manner that, while ensuring a long torsion path, they are guided without further support on the rib (3a) or rib plate (3) until they rest on the rail foot (1a) in the mounting state. The shaping of the strainer (7) ensures for the first time premounting of a strainer on a rib plate (3) without the insertion of the rail from above being hindered. <IMAGE>

Title: Reactor pressure vessel of a water-cooled nuclear reactor installation
Inventor: THIERMANN RICHARD DIPL ING
IPC: G21C13/02
Filed: 1983-11-02
Abstract: In such a reactor pressure vessel, gases collect in the upper plenum after depressurisation of the primary coolant system. They are reduced via a pressure tube by purging with an inert gas. In normal operation of the reactor installation, the pressure tube is warmed to approx. 300 DEG C. This heating damages the control element drives in the vicinity of the pressure tube. Provision is therefore made, on the side of the pressure tube facing the reactor pressure vessel, of a heat barrier which during operation of the reactor installation reduces the convective heat exchange between the reactor pressure vessel and pressure tube, and in the event of a depressurised primary coolant system can be flowed through alternately towards both sides.

Title: Oscillator circuit for a track circuit in railway safety installations
Inventor: HILLEBRANDT FRITZ DIPL ING
IPC: H03K17/95
Filed: 1984-04-27
Abstract: For track circuits in railway safety installations, a special oscillator circuit is designed in which the inductance, which is variable due to influence by a vehicle, of the track circuit is also frequency-determining. The special feature of the oscillator circuit lies in a special control circuit as excitation aid. In detail, the oscillator circuit consists of a resonant LC circuit (AW, C1) with a feedback branch (RW) to a transistor (TR) feeding the resonant circuit. Furthermore, the feedback branch contains a first operational amplifier (OP1) with open-collector output (OK1), the N input (N1) of which is at a constantly low potential and the P input (P1) of which is at a constantly higher potential via a feedback winding (RW) of a transformer (TFR). The open-collector output (OK1) of the first operational amplifier (OP1) is connected to that of a second operational amplifier (OP2), the N input (N2) of which is at a predetermined constant potential, and the P input (P2) of which is connected to a RC section (R8, C2) which can be charged up from a resonant-circuit branch via a diode (D1). <IMAGE>

Title: Electronically controlled quantity-adjustment head
IPC: B65B3/32
Filed: 1984-06-01
Abstract: In the course of automatic material application or automatic material emissions of low-viscosity to high-viscosity media, elements are required which are able to adjust material quantities quickly. The newly developed, electronically controlled quantity-adjustment head is fast and reproducible. An optimum material flow is provided by the piston rod which is drilled to be hollow but is solid in the centre. As a result of the different configurations and sizes of the piston rods in combination with the seating, both very different materials (for example from oils to pastes) and very different quantity flow rates (for example 200 g/min to 1000 g/min) can be controlled.

Title: Computer-controlled tomography device and method for operating it
Inventor: SOHVAL ROBERT
IPC: H05G1/70
Filed: 1984-07-21
Abstract: A device for examining a body with the aid of penetrating radiation is proposed. The device exhibits a source of penetrating radiation for transmitting the radiation through a body and a detector array which is arranged in such a manner that it indicates the radiation after it has passed through the body. The rays emitted by the source pass through the body over a multiplicity of paths and are displayed by the detector. The source has at least two separate point-shaped sources for emitting radiation. The separate point-shaped radiation sources alternately emit radiation. The detector array can be a reduced array of detectors which extends over less than the full diameter of the reconstruction circle. Furthermore, a method for increasing the spatial resolution in a CT scanner is proposed in that the measuring density is increased by radiation emitted by the radiation source being continuously looped in between adjacent rays when the source and the detectors are rotated around the body.

Title: Device for the dropwise dispensing of medicinal liquids
Inventor: KNEER ROLAND
IPC: A61F9/00
Filed: 1985-09-26
Abstract: Medicinal liquids are usually dispensed with pipettes or so-called droppers. For many applications in which only a very small amount is required at fairly large time intervals, these contain an excessively large amount which easily becomes unusable. On use of these containers for application to the eyeballs, application and, in particular, accurate metering are difficult because the eyelids close in reflex. In order to eliminate these disadvantages the invention envisages a device for dispensing very small, accurately metered amounts of medicinal liquids, e.g. consecutively on both eyes, the device comprising a double funnel-shaped upper part 1 whose two funnel parts are combined at their smallest diameters 6 and of which one funnel part 4 can be placed on the body part to be treated whereas the second funnel part 5 is connected to a deformable container 3 for the medicinal liquid sealed by a piercable film 2, the container also receiving an opening spike 8 for piercing the film. In a preferred embodiment for application of eye drops, one funnel part 4 has an oval edge 7 corresponding to the curvature of the eyeball. <IMAGE>
